Genghis Khan... the murderer of peoples

Genghis Khan: This book... There is nothing that happens in this world that does not have a reason. Whoever follows guidance will reach the goal, and whoever strays from the path will fall into the abyss of temptation.
History has no purpose other than reviving the lives of the predecessors, not merely narrating their facts to those who left behind. That is the purpose of these pages, which bring back to life the era of the bloody leader, the murderer of the Asian peoples, the Mongolian monarch: Genghis Khan, that ferocious beast who led ferocious beasts whose cruelty and bravery were unparalleled.
His conquests were a devastating hurricane that relentlessly swept across the peaceful "Transoxiana" and the plains of Khwarezm. It was a hurricane of rained horses that did not know fatigue, trained soldiers who did not know fatigue, and polished swords that did not know mercy, and at their head was their king with a red beard. The banners of destruction gathered above it, and the cries of wolves howled between its flanks. This is an era of human history that is unparalleled.
